The Dooars or Duars (Bengali: ) are the alluvial floodplains in northeastern India that lie south of the outer foothills of the Himalayas and north of the Brahmaputra River basin. This region is about 30 km (19 mi) wide and stretches over about 350 km (220 mi) from the Teesta River in West Bengal to the Dhanshiri River in Assam. The region forms the gateway to Bhutan. It is part of the Terai-Duar savanna and grasslands ecoregion.

Dooars means 'doors' in Assamese, Bengali, Maithili, Bhojpuri, Magahi and Telugu languages. There are 18 passages or gateways between the hills in Bhutan and the plains in India. This region is divided by the Sankosh River into Eastern and the Western Dooars, consisting of an area of 8,800 km² (3,400 sq mi). The Western Dooars is also known as the Bengal Dooars, and the Eastern Dooars also as the Assam Dooars. Dooars is analogous with the Terai in northern India and Nepal.

Dooars

History Of Doars:-

The Dooars belonged to the Kamata Kingdom under the Koch dynasty; and taking advantage of the weakness of the Koch kingdom in subsequent times, Bhutan took possession of the Dooars. This region was controlled by the kingdom of Bhutan when the British annexed it in 1865 after the Bhutan War under the command of Captain Hedayat Ali. The area was divided into two parts: the eastern part was merged with Goalpara district in Assam and the western part was turned into a new district named Western Dooars. Again in the year 1869, the name was changed to Jalpaiguri District. After the end of the British rule in India in 1947, the Dooars acceded into the dominion of India and it merged with the Union of India shortly afterwards in 1949.

Forests and animals:-

The beauty of the region lies not only in its tea gardens but also in the dense jungles that make up the countryside. Many wildlife sanctuaries and national park like Manas National Park in Assam, Jaldapara National Park, Buxa National Park, Gorumara National Park, Chapramari Wildlife Reserve and the Mahananda Wildlife Sanctuary in West Bengal are located in this region.

Other animals includes different types of deer, bison, birds and reptiles. A railway line runs through the tea gardens and the various protected areas and a number of elephants have been killed in collisions with trains.
